General visible light with the same five basic characteristics: radiation, direct nature, reflective, refractive, and penetrating, and far infrared itself with the Sixth characteristics: resonance absorption; when the far-infrared wavelength of the oscillation frequency and the material The same frequency, will produce resonance absorption, the absorption of energy will enhance the molecular vibration and friction heat, the so-called thermal effect [2,3].

In the rolling process, there are definite relations in the following factors: the strip steel rolling time and material, blanks and finished product specifications, tapping temperature, thickness and plate length.
Figure 2 Width specifications schematic diagram of arrangement According to the data given above conclusions, in order to save energy, reduce the preparation time the manufacture plan arrangements should be first prepared in advance on the specifications of the strip, as far as possible to optimize the type of strip material, if possible, it is best to use the same kind material strip.

Assuming that a linearly elastic material,small strains and displacements and a time harmonic exp(-iωt) dependence but without considering external traction,variational model of elastodynamics[11] is shown as: ∫vδέTбdV-ω²∫vδũTρũdV=0 (11) for any kinematically admissible trial displacement field δũ=[δur,δuθ,δus]T.The ρ is density and ∫v·dV is volume integration of the element.

Introduction Ergonomics in an industrial environment is the science of fitting tasks to the workers to effect industrial improvements.
Ergonomics concepts and knowledge were applied to improve this material handling process via the utilisation of new equipment to ease their tasks.
Upon further discussion with the technical personnel, a simple structure made from both new and scrap material was built (Fig.3) for testing use in the workstation.
